PRINT PLATE.

Application filed June 2, 1827. Serial No 196,097.

This invention relates chiefly to cuts for printing and aims to simplifyand facilitate the work of the engraver, whereby routing is obviatedwhen preparing the type surface for printing.

In accordance with the invention a plate is formed by two or more sheetsof celluloid, or other suitable material adhesivel united and ofdifferent color, the surface 0 the top sheet being differently coloredfrom the body of the sheet to enable the engraver to observe the work asthe same progresses, since every line out through the surface stands outin relief because of the difference in color of the body of the sheetwhich a pears through the surface cuts. Moreover, y making certain cutsof a. depth to extend entirely through the top sheet, ortions thereofmay be separated from the ottom sheet to form spaces, thereby obviatingthe accustomed step of routing to form appreciable spaces for highlights in printing.

While the drawing illustrates a preferred embodiment of the invention,it is to be understood that in adapting the means to meet specific needsand requirements, the design may be varied and such other changes in theminor details of construction may be resorted to within the scope of theinvention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof,reference is to be had hereto attache in wh1ch,-

Figure 1 is a top plan view of a'printing block embodying the invention.

Figure 2 is a sectional view thereof on the line 2-2 of Figure 1.

Figure 3 is a view similar to a modification.

Figure 4 is an enlarged detail sectional view, the dotted linesindicating a portion of the top sheet pried loose from the bottom sheet,to provide space usually formed by routing.

The numeral 1 designates the block or other backing upon which the typeplate is mounted. In forming the type plate in accordance with thisinvention a plurality of sheets of suitable 'material are; placed oneupon the other. and adhesively united by a suitable cement. The sheetsmay be of any thickness and usually consist of celluloid or ana ogouscomposition. The top sheet is designa d by description and the drawing.

Figure 2 of a the numeral 2 and the bottom sheet by the numeral 3. It ispreferred to have the top sheet 2 of a less thickness than the bottomsheet 3, therebyobviating the necessity of making a deep cut when it isrequired to remove a portion or portions of the top sheet to form spaceswhich ordinarily are provided by routing. The sheets 2 and 3 are ofdifferent colors, the bottom sheet 3 being dark and the top sheet light.It is preferred to have the top sheet 2 white and covered by a darkcoat, .which, when out through, exposes the white body of the top sheet,thereby enabling the engraver to readily observe the work as itprogresses, because of the white line standing out in relief by contrastwith the dark surface. When portions of the top sheet 2 are to beremoved to provide spaces, the cuts are deepened to extend through thetop sheet 2 so that the portion to be removed may be separated from thebottom sheet 3, as indicated by the dotted lines in Figure 4, whereby toform the space corresponding to the is flexible and may be readilyapplied to a curved platen or like surface to which it may be secured'inany determinate way.

In the modification shown in Figure 3 a sheet of paper 5 is interposedbetween the sheets 2 and 3, and operates to facilitate the removal ofthe part or parts 4 of the top sheet when it becomes necessary toprovide spaces in the printing surface.

Having thus described the invention, I

claim 1 f 1. type plate comprising a p urality 0 sheets adhesivelysecured, the top sheet being adapted to receive the engravin and to haveportions removed by being cut t rough to the next sheet and separatedtherefrom.

2. A- type plate comprising superposed sheets adhesively united, thebottom sheet being of a dark color and the top sheet being of a lightcolor and covered with a dark coatpress v employed. It is observed thatthe type plate ing, which, when out throu h,exposes the engraving inlight lines, an said topsheet adapted tohave ortions removed therefromwhen out throug to the adhesive joint with.

the next sheet.

B'I A- type late comprising a plurality of superposed sheets adhesivelyunited and of contrasting color, the bottom sheet being dark and the topsheet light and covered upon its top side wlth a dark coating, throughwhich the engraving iscut to expose the light material comprising thetop sheet and the latter having cuts extending therethrol g i and theportion circumscribed removed to provide a space for the high light inprinting.

4. A type plate comprising superposel sheets of celluloid, or analogousmaterial, adhesively united with a sheet of pa er therebetween, thebottom sheet being ark and the top sheet light, and covered by a darkcoatingsthrough which the engraving extends and having a portion removeto provide the space for high light printing.

In testimony whereof I afiix my signature.
